Cacapava Wellfield Project

Implementation of a wellfield in Caçapava, SP, Brazil. This project is a final assessment of a undergraduate class named: Water and monitoring wells for groundwater

This project was designed and carried out with the collaboration of:

• Cleilson Lopes
• Matheus Lima

🚧 Work In Progress 🚧

---

Objective

• Implementation of a wellfield with its constructive parameters in the municipality of Caçapava to meet the demand of a possible abrupt population growth of 20 thousand people.
• Define the best area to construct the wellfield.

---

./data/ folder contain the data used in this project:

• dados-daee.csv well data from DAEE
• dados-siagas.csv well data from SIAGAS
• IRITANI-data.csv well data from Iritani, 1999

./groundwater_recharge/ folder contain the workflow file used to estimate the groundwater recharge in Caçapava-SP. Here was used the Thornthwaite-Mather Procedure (Thornthwaite and Mather, 1957). The groundwater recharge map are here

./reports/ folder contain the reports of progress presented in the class.

./results/ folder contain the maps produced to delimite and define the wellfield.

./transmissivity/ folder contain the files to estimate the transmissivity from the available data:

• T-estimation.py transmissivity estimates using welltestpy 🚧 (Work in progress) 🚧
• Sc-T.ipynb transmissivity estimates using empirical method that relates transmissivity and specific capacity (Mace, 2000)
